The Five Pillars of Red Hat OpenShift Observability It is with great pleasure that we announce additional Observability features coming up as part of the OpenShift Monitoring 4.14, Logging 5.8, and Distributed Tracing 2.9 releases. Red Hat OpenShift Observability’s plan continues to move forward: as our teams tackle key data collection, storage, delivery, visualization, and analytics features with the goal of turning your data into answers.

This post was written in collaboration with Alex Blinov, senior engineering manager at Oracle Cloud Infrastructure and David Campbell, IC-3 senior member of technical staff at Oracle. Recently, Red Hat and Oracle announced our expanded collaboration to Bring Red Hat OpenShift to Oracle Cloud Infrastructure. We’re pleased to announce Red Hat OpenShift on Oracle Cloud Infrastructure with Virtual Machines (VMs) is available for Developer Preview.

In today's rapidly evolving tech landscape, two technologies have been making waves: WebAssembly (WASM) and OpenShift. While they serve different purposes, their combination can lead to powerful, scalable, and efficient applications. In this blog, we'll explore how WASM and OpenShift can work together and why this pairing is significant for modern developers. WASM is available as a developer preview feature in OpenShift 4.14.

Red Hat OpenShift, the most popular container orchestration platform, has always been about flexibility, scalability, and resilience. As workloads evolve, so do the requirements for resources such as CPU and memory. Traditionally, adjusting these resources for a running Pod meant recreating the Pod. However, with the concept of in-place resource resizing, this is changing. Let's dive into what in-place resource resizing is and why it's a game-changer for OpenShift users.

The phrase “Kubernetes secrets are not secrets” is commonly heard, but what are these secrets and why are they important? Secrets refer to sensitive data such as passwords, certificates, bearer tokens, and more, which are essentially the core assets for an application owner. Compromising these secrets risks not only the application but potentially the entire infrastructure, underscoring the need for secure storage and management.

In a Kubernetes cluster, the control plane's stability, resiliency, and performance drive the overall cluster stability, resiliency, and scalability. Generally speaking, the various components of Kubernetes are stateless. For storing object or artifact definitions of a cluster, the etcd key-value store acts as the single source of truth and as the only stateful component. This distributed key-value store is both reliable and strongly consistent.

In the realm of managing large networks of Single Node OpenShift (SNO) clusters at the Far Edge, the challenge of upgrading systems efficiently is a task that carries substantial weight. The intricacies of this process often involve navigating tight maintenance windows, grappling with limited bandwidth (particularly in OAM networks), and coping with high round trip packet latencies. Within this context, the importance of reducing the time consumed to upgrade clusters becomes evident.

Historically, Kubernetes storage drivers have been delivered as “in-tree” plugins where the drivers lived and were shipped as part of the Kubernetes core payload. Over the past few years, the in-tree approach has transitioned to a new standard called Container Storage Interface (CSI) where the driver’s code lives outside of Kubernetes.

OpenShift users have many options when it comes to deploying a Red Hat OpenShift cluster. Whether installing on-premises, in the cloud, or to your own hybrid configuration, OpenShift has integrations to help your journey. Today we are pleased to announce a new platform type to enable partners to achieve varying levels of integration not previously possible in OpenShift: the external platform. What is the External Platform?

Red Hat OpenShift Service on AWS (ROSA),  now supports OpenShift Virtualization enabling the ability to rapidly migrate full virtual machine images to kubernetes pods within the cloud and automate them like containers.
